MacArthur Boulevard lane closures expected through June 17 in Bethesda

Anticipate single-lane closures on two-lane MacArthur Boulevard in the Bethesda between today and June 17, 2024. The closures will be in the area between Goldsboro Road and Walhonding Road on weekdays between 9:00 AM and 3:00 PM. U.S. Army Corps of Engineers Washington Aqueduct crews will be repairing the Old Conduit aqueduct, the 9' diameter tunnel that has been transporting water from the Potomac River to the Dalecarlia Reservoir since 1863. The Corps reports that inspections (see photo above) have raised structural integrity concerns, damage blamed on violations of vehicle weight restrictions on MacArthur Boulevard, which sits above the aqueduct.
